HIGHLIGHTS

global

Added the LC2403A device.

Added LC2402A to the 64-pin TQFP PAG package option on the Features page.

Changed MIN Conversion Time for the ADC from 375 or 500 ns to 500 ns on the Features page, in Table 1, in the

ADC absolute maximum ratings table, and in the internal ADC module timing parameters table.

Added PAG to the LC2402A column in Table 1, Hardware Features of 240xA Devices.

Changed seven interrupts to six core-level interrupts in Table 4.

Changed the description for IFR in Table 4.

Changed the formula for deriving the digital value of the input analog voltage

Added a note concerning the need for an external 1-M-

Ω resistor across X1 and X2 terminals.

Added note on lead-free package to Figure 20.

Changed MAX value for ADC module current in current consumption by power-supply pins over recommended

operating free-air temperature ranges for both operational and low-power modes.

Added a note to Figure 27

Changed the IDD current specification for ROM parts in LPM2 mode.

108

Changed DNL/INL information for LC240xA parts. There is now one table for both Flash and ROM parts.
